TO WHOM IT MAY CON CERN:

Be it known that we,-WII.LIAM I). HARRELL and HARRY M. HALL, both of Osgood, Ripley county, Indiana, have invented a new and useful Fly-Fan g and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification Our invention relates to a device for working one or several fans, for the purpose of creating a current of air and driving away insects. v

Figure 1 is a front elevation of a machine embodying our improvements.

.Figure 2 is a side elevation ofthe same. y

Figure 3 is a partial elevation, showing our maehineinverted for a simply rotary motion.

l Upon the cent-re ot` a base, A, is erected a stud-shaft, B, for a revolving frame, C. Aixed eoncentrieally to thev said stud-shaft, or to said base, just below the revolving-frame C, is a spur-wheel, D, which, through suitable gearing E, connectedtoa mainfspring, F, causes the revolution of the said frame and its appurtenances Whenthe spring is Wound. G is a square'arhor for winding up the spring. His a'sliding-bolt for stopping the rotation of the frame C when desired. This bolt being pushed inward, arrests the rotation of the frame C by impingement of the said stop with the arbor G. vThe base A has one or more holes or sockets afor the insertion of the stems of as many fans I, when the machine is used in what we term its inverted position, (see tig'. 3.)

The upper portion ofthe frame C ali'ords journal bearing for another spring, J, which, through the medium of suitable gearing K journalled in'said frame, rotates an eccentric, L, which causes the vibration of a yoke, M, having projecting arms N N', to which sockets O O', for as many fan-stems P P', are united' by rather stiil hinge-joints n, so the fansv can be adjusted to'a greater or less degree of elevation or depression, (see red lines iig. 1.) The yoke is suspended to the frame by a shaft, m. Q, is a hook pivoted to the frame, `and whose engagement over one of the arms N arrests, 'when desired, thevibration. It will he seen that' the fans can be set to either an elevated o1' depressed position, and either vibrate'l `without rotating, or rotated without vibrating, or both rotated and vibrated at pleasure. Also thefaus, being set with planes at a greater or less obliquity with their plane either ot' vibration or of rotation, avail themselves of the atmospheric resistance to modify or control the velocity of either of these distinct motions.

We claim' herein as new, and of our invention- 1. The arrangement of base A, studshaft B, andrevolving frame C, furnished with two distinct sets of vclock-workior reciprocating and horizontally rotating motion of one or more fans, either singly or combined as set forth. p

2. The provision of tho hinged connections of the fan-arms for the purpose stated. 3. In combination with the subject of the first clause, we claim the stops H and'Q for arrestingthe rotary and vibrating motions of the fans, either jointly or severally. i

In testimony of which invention we hereunto set our hands.
